STOVE CONSTRUCTION.

Application filed April 3, 1925.

This invention is concerned with stove constructions and more particularly stoves of the gas range type. The general ob ect thereof, is the provision of a top or canopy construction embodying an assembly of panel members in a novel manner whereby they may be finished with'a vitreous enamel and thereafter be assembled into a very rigid and sanitarystructure.

A further object of-my invention is the 'provision of novel canopy construction The essential characteristics are summarized in the claims.

In the drawings Fig. 1 is a front elevational perspective view of a gas range embodying the features of my invention; Fig. 2 is a plan view of the stove; Fig. 3 is an end elevational view of the top or canopy part of the stove; Fig. 4 is an enlarged cross-sectional view taken substantially along the lines 41 of Fig. 2; Fig. 5 is anenlarged cross-sectional View transversely of the hood portion of the stovesubstantially along the with one of the elements of the top structure reversed and Fig. 7 is a cross-sectional: detail taken along the line'-77 of Fig. Fig. 8 is a fragmentary sectional view taken along the line 8-8 on Fig. 4.

It is the present practice of stove manufacturers to offer to the prospective pur-' chaser gas ranges which are constructed in such a'manner that all of the parts or panel members thereof may be finished in a neat "manner. This finish usually comprises a vitreous coating of burnt enamel of a light color;

economical shaping of the sheet metal and the 5 lines 55 of Fig. 2; Fig. 6 is a fragmentary cross-sectional view similar-to Fig. 5 but member flanges 24 which 'are'provide'd with an inturned portion 25 parallel withthe sur- My invention contemplates a top construction for such gasranges which involves but finishing thereof by coating the shaped mem Serial N0. 20,359.

bers with a vitreous enamel, the assemblage being such that all parts of the panel members are readily accessible for the purposes of cleaning. In Fig. 1, I show a range comprising a base 10 supported by legs 11. The base supports acombined broiler and baking oven construction 12, a warming oven 13 at the side thereof and an open burner box 15 beneath which are arranged burner pipes 16. A back panel 17 and a shelf 20 are provided to complete the appearance of the stove structure proper. The back panel and shelf are provided with an end bracket 18 to which they are attached along one end, while the other ends thereof are attached to the oven construction 12. The shelf 20 is usually mounted with the top surface thereof level with the top surface of'the oven structure 12 and this shelf member is secured to the bracket 18 and the oven structure 12 as well as'the back panel 17.

To the foregoing described range construction I propose toattach a top or canopy construction in such a manner that the stove may be merchandized with or without such top and this canopy construction'may comprise panel members formed in a particular "manner to facilitate the coating'and baking thereof in an enameling furnace and the particular shape of each panel memberis such that undue warping is prevented during suchenameling process. The construction may therefore comprise a single back panel member 22 extending longitudinally at the upper back of the stove and side or end panel members 23 surmounted by a top 30. The end panels may have facesof the panel members 23. 'The rear vertically extending edge of the panel members 23 may be provided with inwardly exextending flanges 27 formed to be parallel with the surface of the panel 22'and spaced therefrom to provide portions extending at right angles thereto. These end portions af- '20 and to the bracket member 18, in a manner shown in Fig; 4. Any suitable means may serve 'to connect the shelf 20, panel members 23 and brackefi 18 together, such tending flanges 26 which engage vertically as stove bolts 19. The lower portion of the back panel member 22 may be suitably secured to the back of the oven structure 12 and the shelf 18. V V

The top edges of the end panel 23 and back panel 22 are flanged to lie in a common plane and thus provide a support forthe top structure which is preferably formed of a single drawn sheet metal member of the general form shownin Figs. 1, 2 and 5 The top closuremay comprise a single top member of the 'particularshape shown to promote the sanitary, neat appearance and to obtain a structure which may be shapedto stand a baking temperature when the surfaces thereof are enameled and whereby the warping thereof may be prevented. A

particular shape fulfilling these requirements comprises an inverted pan-shape having a flat top and flaring side andiend portions 31'and 32 respectively, The side i portions 31 and the end portions 32 are prov to vided with a continuous rectangular band Vflange 33 extending completely around the bottom of the canopy member and this flange may terminate in a bead 34 extending along the front. ;The rear thereof may be provided with a horizontally extending flange 36 which affords bearing contact with atop flange 22 formed on the back panel member 22. Suitable-means such as stove .bolts 40 may serve to hold the flanges of the respective members together. 7 i

The top edges of the end panel members 23 may be provided with set-in portions 23 forming a bearing or support for the enjd i i Y beads 34 formed on the top canopy member.

These setsin portions terminate in horizontally extending flange portions 23 contact ing with side stretches of the beads. 34. In order to effectively conceal the means for clamping the canopy to themembers 23 1 preferably form notches 3& in the edges of the material which is finally folded over to form thejbead as shown .in Fig.3. Bolts38 having rounded nuts may serve as clamping members, the heads of the bolts being concealed by the bead by reason of the notches;

allowing the heads to drop down as shown in Fig. 4.

It W111 thus be seen that the particular flanged shape of the end panel. members 23 and the back panel member 22 affords an assemblage in the stove which conceals most of the stove bolts and these particular shapes afforda very rigid structural relationship and also are conducive to economical finishing or enameling of these members when subjected to vitralizi-ng temperatures during the course of manufacture. During such periods the flanged portions of the panel members serve rto prevent undueswarping thereof. This particular shape of the top canopy member is desirablefor the reason that it may have the inner and outer surduring the burning period.

faces thereof coated with a vitrolite and the particularshape is such that even when this member is subjected to a red heat temperature, slumping or warping of the panel portions-thereof,-will not take place. Furthermore, it will be noted that the bottom edge or margin of this top member is formed to lie in substantially a common plane whereby the entire piece may be suitably supported This particularshapealso is conducive to a very rigid assembly between the top member and the end members comprising the canopy structureof the stove.

i In Figs. 5and 6 I show a flue fitting 45 to which a flue pipe for the escape of burnt gases may be attached By forming the flaring portions of the top member at an angle of substantially 425 to the top panel portion thereof, the fitting 45 .may be attached'thereto in such manner as to afford attachment for a horizontally or a vertically extending flue pipe. Hence by forming the fitting with an end surface at an angle relative to the center line thereof equal to substantially 45 degrees theflue fitting 15 may be reversible in its position as shown in Figs. 5 and 6 andI accordingly show perforations in the backportion 31 of the top member which may register with suitable openings formed in a brazed flange 45 formed on the fitting 45 whereby the stove bolts 18 may extend therethrough to secure the fitting in removable manner tothe canopy construction. 3 p
